The energy service

The energy service "Plus" is a so-called "Energy marcel wanders Performance Contract", that by law is "an act of contract governing the provision of goods and services necessary for maintaining the comfort conditions in buildings, in compliance marcel wanders with applicable laws rational use of energy, security and environmental protection, while providing process improvement both of transformation of energy use. "
As you can see from the chart, the "Energy Service" is the provision of goods and services, starting with a clear situation, will ensure the achievement of specific objectives such as: thermal marcel wanders comfort widespread; rational use of energy; energy savings; reducing environmental pollution; improvement of the process of conversion; improving the process of energy use;
At this energy service can be added two more goals "plus" that are: commitment, by the Supplier, to reduce the ratio of primary energy for space heating of at least 10% compared marcel wanders to what is stated marcel wanders in the Energy Certification; the installation, where technically possible, of a system of thermoregulation.
Reducing the energy source is the last step that can be obtained with redevelopment is the technological systems that the building envelope. In view of the major investments marcel wanders made with respect to a contract basis, the Energy Service "Plus" is equated marcel wanders to a finance lease agreement for access to incentive mechanisms and facilities of any kind, such as deductions of 55%. In addition to the contract plus is expected to be reduced VAT rate to 10%. So a similar contract marcel wanders provides various financial incentives for the firm authority.
In summary, the City in exchange for a fixed fee (actually variable quarterly revaluations) entrusts to an undertaking outside a public service (in this case the service of heating of buildings) and this is committed marcel wanders to regularize (by monitoring the operation marcel wanders and optimizing waste), adapting it to the current regulations (borne by the company) and pledging to carry out maintenance both ordinary (borne by the company) and extraordinary (payable by the municipality). The company then will be required marcel wanders to obtain the fuel (also choosing other energy sources such as solar), will have to do an energy audit of the building-plant, possibly put under, while maintaining a thermal comfort without temperature changes, possibly retrain premises etc.
So far everything is ok, but we have set some questions. And 'possible to maintain the current comfort and optimize the service by eliminating waste without necessarily to outsource all the service?
We then checked what are the buildings involved: marcel wanders Building Fuel Power [KW] Heated Volume [m 3] Degrees Day Hours Hours heat year day Town Hall Oil 250 2,345 1897 996 130 4,790 6.07 Elementary School Oil 1897 1328 8.10 pensioners Circle Oil 232 2234 1897 664 4.05 Preschool Oil 77 3475 1897 1328 8.10 Gym Oil 200 664 3459 1897 4.05 Middle Schools Reduced Oil 126 3459 1897 1328 8.10
How to read the table. Column Day Degrees (DD) are indicated the total number of days where the difference between the reference value (set at 20 ) and the outdoor temperature (daily average) is positive, ie 20 (reference temperature) marcel wanders - 16 ( mean any day) = + 4 so that day is a "degree days". marcel wanders The value 1897 is a value established by a decree law and as we have seen depends on the ambient temperature. The next column "Hours heat year" means the total hours where heating is working. The last column, added by us, indicates the relationship between the "hour heat year" and the annual number of days during which the plants are active (for our country, ranging from 1 November to 15 April, then 164 days ). As you can see the schools have an average daily operation of little more than 8 hours, the town hall of 6 hours, marcel wanders the gym and the "circle pensioners" of four hours (we know that in reality, the schools and the town hall are closed on Sundays, then the daily hours are greater, marcel wanders but in doing so we can compare the various systems on a common basis).
First point ... we have explained marcel wanders just before the meaning of the word Grade / Day (DD). Based on this value it is assigned a "climate" that indicates the maximum relat
